Often, bugs and issues in this class are so common as to be blithely overlooked! Beware, they remain very dangerous; take care to find, understand, and fix them.
All classes of overflow and underflow bugs on memory buffers are carefully documented and tracked via the Common Vulnerabilities and Exposures (CVE) and the Common Weakness Enumeration (CWE) websites.
